“We could be in automotive production in a year and a half.”

 
Envia Systems, a battery maker based in California, announced on Monday what it called a “major breakthrough” in lithium-ion cell technology that would result in a significant increase in the energy density — and a sharp reduction in the cost — of lithium-ion battery packs. Envia is financed by the Energy Department and G.M. Ventures, the venture-capital arm of General Motors, as well as other investors.

“We will be able to make smaller automotive packs that are also less heavy and much cheaper,” Atul Kapadia, chairman and chief executive of Envia, said in a telephone interview. “The cost of cells will be less than half — perhaps 45 percent — of cells today, and the energy density will be almost three times greater than conventional automotive cells.”

Mr. Kapadia continued: “What we have are not demonstrations, not experiments, but actual products. We could be in automotive production in a year and a half.”

Envia, which was founded in 2007 and has licensed some technology from Argonne National Laboratory, was awarded $4 million in late 2009 by the Energy Department’s ARPA-E program, which finances advanced energy research. As a founding principle, the program was designed “to develop lithium-ion batteries with the highest energy density in the world.”
